The zone holds UTC−3 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 12h 16m of daylight. The shortest is 22 June, with 11h 58m. The swing between them is 18 minutes. Within a few degrees of the equator the length of the day barely moves all year.
The earliest sunrise and the latest sunset do not land on the longest day. In São Luís the sun comes up earliest on 6 November at 05:35, while the latest sunset waits until 9 February at 18:17. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In São Luís that civil twilight runs about 21 minutes at the equinox.
